To all whom .it may concern?.

Be it known that I, HOW''RD B. SHERMAN,

`of Battle Creek,'in the county of Calhoun and,

State of Michigan, lhave invented certain new and v useful 'Im roveinents in Hose-Clamps and I 'hereby ecla're vthat the followin' 'is a full, clear, and exact description thereo ref ,ference beinghad to the accompanying drawings,*whi'ch'form parto'f this specification.

This invention is` an improvement in hose Stain ed outof sheet or strap -i'ne'talv and is especia ly-designed to'be formed out 'of 'heavy or tough' metal such as bar or sheet steel which is too thick Land tough to be' easily 'dis-f placed or swaged in diesL-" y -One object ofthe invention is to provide such' clamps with an attached tongueto bridge the space between the ears of the i clamps and prevent'puckering or bulging of "the hose between`tlie'ears; and this part' of the invention has particular'referenceto the formation of such taching the same to the clampfband.'

' i ,The invention is also-designed to provide recessfor the" accom" the clamp band witha p modation ofthe free end of the" said' tn uev and to provide' this from projecting' out of the clamp;- and said Iguard prevents the end of the tonguefcatching upon exterior' objects, and imparts a I more symmetrical a pearance to the clamp. The invention vwi be clearly understood byfreference. to the clamp shownin the-accompanying drawings and the following description thereof. i

' said drawin of the complete c amp. Fig. 2 is atop view thereof, the bolt and ynut| being removed. Fig. 3 is a central section therethrough. Fig. 4 is a' transverse section on line4 -4, Fi V3. Fig. 5 is an enlarged transverse section onine 5-5, Fig. 3. j y

The body A of the clamp can be made from bai. steel or any other suitable metaljfsteel being atpresent preferred, obtained in stra form o'f the desired-width. A suitable'lengtli iscut from such strap to form the clamp body'and it is then subjected to the action of proper dies by which one or more slots (1, 1b,-as shown) are cut in the metal for the purpose of lightening it and insuring its hold upon the hose. The dies (not tongue and the modeof at-A recess 'withl a guard `whereby .the end of the tongue is vprevented `si-.-Figure'l is a side viewbecause it can bethe body the body is punched s'o as to form e l channel l? on its inner side, but the metal disj placed to form this channel is not punched enl tirely away from the body but only cut'loose therefrom at the sides of lthe channel as shown at 1 C. The endsof the partially punched away portionZ remain.- integrally connected with the' body of the' clamp, but the main portion of art 2 "is forced out sufficientlyv from the [bo y to'formachannel ll on the interior of the body as shown; but said channel is `covered i and guarded externally by the' partly |'severed portion or guard 2. The channel 1e is fprovid'edy lfor thefaccoininodation of the free 'ei'id"of'tl`1e"toiigi1`e 3 hereinafter referred to.'wr The fort1on'2 tl'ius'forinsl a guard which protects t efree end pf the tongu'fvand -pr'e ventsitprojeeting'through the channel 1e to theoutside of the clamp and catching on exterior objects.' i'

The tongue 3 is subjected to considerable strain as the clamp is tightened upon the hose and.by making it concave-convex in cross section it is liable to distortion under pressure and will which is adjacent e manufacture of curved lonclosure between the ears.

The free end of the tongue 3 is preferably pointed or thinned as shown at 3, by being hammered or ground off, to enable it to enter and move more readily in the channel while the clam is being tightened upon the hose,
